China Maritime Studies Institute – “Damage control” (sunhai kongzhi, or just sunguan) refers to measures and actions taken by a warship for the prevention, control, and elimination of damage in order to maintain or recover its vitality (shengmingli). If a warship suffers an accident, this could result in major casualties among the crew and cause damage to the ship’s equipment; it might also impact the ship’s vitality. The crew’s normal level of damage control training determines the success or failure of damage control. In order to fully leverage the active role of crew members in damage control and fully leverage the effectiveness of damage control, a scientific and rational damage control plan must be prepared. The damage control plan resolves questions related to the deployment and responsibilities of personnel during the damage control process, according to certain principals and requirements.
